CHIMNEY.

SPECIFICATION forming part of Letters Patent No. 265,386, dated October3, 1882-.

Application filed May 24, 1882. (No model.) I

To all whom it may concern Be it known that I, OTIS B. OOLGORD, of

Greenville, Bond county, Illinois, have made a new and usefulImprovement in Chimneys, of which the following is a full, clear, andexact description, reference being had to the an ncxed drawings, makinga part of this specifieat-ion,iu which- Figure 1 is a side elevation ofthe improvement; Fig. 2, a sectional elevation, and Fig. 3 a horizontalsection taken on the line 3 3 of Fig. 1.

The same letters denote the same parts.

The outer air-currents are liable, as is well known, to interfere withthe proper working of a chimney. To obviate this difliculty is the aimof the present improvement, which consists in providing the chimney withtwo or more outlets, the outlets beingso spaced apart, shaped, andrelatively arranged to the main flue as to cause any air-currentdescending one of the outlet-fines to strike across the main fine andpass into, through, and out of the opposite outletflue, and in so doinginfluence the smoke in the main flue to escape therefrom and pass ofifwith the ascending air current. To this end the outletflues are notextended so as to be directly over the main flue, but are out of linetherewith and on opposite sides of the main fine, and at theirlower-ends are bent or turned so as to cause the descending aircnrrent,after reaching the lower end of that one of the outlet-fines in whichthe air-current chances to descend to shoot across the main line andinto the opposite outletflue, as described.

As seen in the drawings, where A represents a chimney of the usualdescription, saving as modified by the prcsentimprovemen t, B Brepresent the outlet-fines.

The working of the improvement is based upon the fact that the outer airblowing downward toward the main flue does not enter the twooutlet-fines with equal force, the eftect of which is to cause adescending current in one of the outlet-fines and an ascending currentin the other outlet-flue. In the drawings the current is supposed to bedescending in the outlet-flue B and tobe ascending in the outletflue B,as indicated by the arrows, and the smoke is being drawn from the mainflue a and into the outlet-flue B and carried off with the ascendingair-current in the last named outletflue.

The outlet-tines B B may be built so as to be in one piece with thechimney A; or the flues B B may be constructed as an attachment to beapplied to chimneys. In the last named case a desirable form ofconstruction is that shown, the attachment consisting of the uprightportions 1) b, united bya horizontal portion,'b and having an extension,to fit into the main flue a. The two parts I) I), however, may be madein the form of elbows and he inserted into or connected with the maintine a at opposite sides thereof; or, further, the attachment may be inthe form of a tube of semicircular or approximate shape, the essentialof any form of the attachment or improvement being a flue so shaped thatthe entering aircurrent shall descend and strike across the main flue.

I claim-- 1. The combination, with a chimney, of the outlet-tines B B,said outlet-fines being out of line with the main flue, and at theirlower ends being closed to the outer air and bent or turned to cause anycurrent descending through one of the outlet-fines to shoot across themain flue and ascend into the opposite outlet-flue, as and for thepurpose described.

2. A chimney attachment consisting of the outlet-fines B B, saidoutlet-fines being outot' line with the main line, and at their lowerends being closed to the outer air andbent or turned to cause anycurrent descending through one the opposite outlet-flue, as and for thepurpose described.
